Calibration Of Collimated Flash Tester For High‐Concentration Photovoltaic Panels

Accurate high volume manufacturing final test of high‐concentration photovoltaic (HCPV) panels is challenging owing to the spectral sensitivity of multi‐junction solar cells, the inherently small angular acceptance, and the elevated temperature during standard operating conditions (CSOC). An industrialized HCPV solar simulator developed in parallel with SolFocus first generation SF‐1000S product has been previously discussed. Validation of the regression of simulator performance measurements from test conditions to CSOC was achieved by correlation of solar simulator and on‐sun results using more than 100 SF‐1000P panels.The second generation SF‐1100S product incorporates a number of design and manufacturing advances including more efficient multi‐junction solar cells, more thermally conductive receivers, more transmissive collection optics, and an optimized backpan, as well as a larger collection area. Each of these improvements can affect the accuracy of the regression from simulator test condition to SO...
